Your RoofIQ Risk Report

Four rooftop units, read from data plates and confirmed by aerial survey: what you have, what drives its cost, and what a failure costs.

This is a sample. The client, the site and the figures are a composite, published so you can see exactly what a RoofIQ Risk Report contains before requesting one. Every report is built the same way: from your equipment list, or from aerial imagery and public records if you do not have one. No site visit, three business days, no cost.

Step 1 of 4Property & asset overview

A single-story flex building in northwest Houston. All four units are landlord-owned, in place at lease inception, with the repair obligation on the tenant.

Aerial view of the rooftop with the tenant premises outlined and RTU-1 through RTU-4 annotated
RTU-1 through RTU-4 are the assets covered by this report. The other rooftop units on this building serve neighbouring tenants. Mapping is likely rather than confirmed, pending verification of unit tags on site.

Step 2 of 4Cost and risk factors
01

Your building is easy on equipment. Your lease is not.

Distribution and light industrial is the gentlest occupancy for rooftop HVAC: low internal load, no kitchen exhaust, no process heat, long stretches near-empty. How you use the building runs in your favor.

Relative annual maintenance and repair spend per rooftop unit. Excludes replacements and capital projects.

The lease does not. The landlord owns the equipment; you pay to keep it running. Whoever would fund a replacement never sees that cost, and whoever pays it cannot replace an asset they do not own. Expect these units to outlast the point where replacing them makes sense.

One unit is past life. One is nearly new.

Against an 18 year expected life, RTU-4 sits at 33%, RTU-3 at 61%, RTU-2 at 83% and RTU-1 at 133%. Past year ten, frequency and severity climb together and the constraint shifts from parts wearing out to parts getting scarce.

The same repair costs more every year. Yours sit at the expensive end.

Every input on a repair bill is rising, and contractor markup compounds supplier increases before they reach you. Three of your four units run on refrigerants being phased out, which is where parts are scarcest and quotes highest. A repair quoted today is the cheapest it will ever be.

Illustrative index built from regional service pricing.
Parts
Major OEMs raised commercial parts pricing up to 8% in 2026, largely on tariffs.
Labor
Rates climb against a tightening trade labor pool, and the truck roll bills the same whether the fix takes an hour or five.
Scale
At four units you carry no volume leverage. Nobody discounts a four-unit account.
Refrigerant is the sharpest edge. Installed cost has roughly doubled in three years as EPA allocations step down. RTU-1 runs on R-22, banned from US production in 2020, so parts for a 24-year-old unit are often unavailable. RTU-2 and RTU-3 run on R-410A, a decade behind: new equipment ended January 2025 under the AIM Act, supply tightening 85% by 2036. Only RTU-4 is on the current standard.
04

Gulf heat runs long, and never lets up.

Your units carry cooling load nine months a year, peaking in August. Unlike a dry climate, humidity holds overnight temperatures up, so compressors run through the night instead of unloading. Salt-laden humid air accelerates corrosion on coils, cabinets and electricals.

RTU-1 has no middle. With no like-for-like part available, its next major failure goes straight from a $600 service call to a full replacement. That gap, not the age, is what makes it terminal. Repair figures are frequency-weighted across 31 rooftop failure modes; replacement is costed at $2,700 per ton installed.

Step 4 of 4Cost certainty program
The program

Your repair spend, locked flat. One number for all four units.

Four units cannot average themselves out. One compressor is your whole year. We take that variance onto our book and hand you a fixed price. You keep your provider; we review and pay the invoices.
